Like every electromagnetic wave, radio waves in a vacuum travel at the speed of light, and in the World's climate at a nearby, however somewhat lower speed. Radio waves are created by charged particles going through speed increase, for example, time-fluctuating electric currents. Normally happening radio waves are discharged by lightning and cosmic articles, and are important for the blackbody radiation produced by every single warm item.
